Apple Watch Cellular & eSim - What you need to know| iStore Online

Stay connected with Apple Watch, even when you’re away from your phone.



Introducing Apple Watch Cellular. Take calls and access data on the go from your wrist - without your iPhone



So, how does the Apple Watch eSIM work?

An eSIM is an embedded SIM-card which is used for devices that have eSIM capabilities which cannot be removed from the device, in this case, the Apple Watch. The linked Apple Watch devices will use data, SMS and voice bundles from the primary billing account linked to your iPhone with a traditional SIM card. 



Before you can setup the eSIM, you need to ensure your Apple Watch GPS & Cellular is paired with your iPhone. Make sure that you have an iPhone 6s or later with iOS version 9.0 and upwards.


Open the pre-installed Apple Watch app on your iPhone and follow the steps.
